post spacing on very low deck

I am planning to start a 10' x 14' deck beside my current concrete patio and wondered if I need additional support posts on the inside? I had originally planned to have one in each corner and in the middle on all four sides along with a center one, but thinking that is a little overkill now. thoughts?

What size lumber are you using for joisting? 2x10 would be optimal, 2x8 minimal for deflection purposes at 10', although 2x6 will "legally" span 11'. Are you running your joists perpendicular to the structure in the 10' direction?

which edge is beside the concrete patio. i would install the top deck parallel to the patio.
is any edge by the house.
9 posts seemes great to me .
more post lets you use smaller joist and beams.
what are you using for a top deck? 5/4 x 6 ?

How much space is there going to be under this deck? Wood needs to breathe so being too close to the ground encourages rot.

it will be 10 ft out from house and 14 along with the house. the decks first 2 ft from patio will be level and just step up the last 12 ft. It will be a good 12 inches off ground on main part of deck. Planning to do the outsides of deck in 2x8 and use 2x6 for joists in between. running the joist parallel with house so they will be a lil less than 12ft long.
